Forrester published a new report today making the call that the iPad challengers that have been announced so far—Android Honeycomb tablets from Motorola, Toshiba, and others, as well as the BlackBerry PlayBook and HP TouchPad—are solid products with fatally flawed product strategies.

In short, competing tablets are too expensive, and can’t match the Apple Store as a channel. These two claims are related: Forrester’s research has shown that consumers attribute more value to Apple products because of the in-store service. Consumers are not only comparing feeds and speeds; there’s also a human factor. The humans working in the Apple Store will have a huge impact teaching consumers about the iPad and how to use it. Compare the experience of walking into an Apple Store, where the iPad is front and center, to walking into a Verizon store where the Samsung Galaxy Tab is collecting dust at the back of the store and the sales reps don’t quite know what to make of it. Or walking into a Best Buy store, whose shelves will soon be lined with similar-looking tablets with similar functionality.
